[. . . ] The best we can do to try to help you eliminate hum, oscillations, or other stray characters from your system is to tell you to experiment. If you think lifting the ground on the MP 24z, crossovers, equalizers or power amplifiers might help, go ahead and try it. There is science involved in de-humming a system, however it is sometimes faster to just experiment. Occasionally, directly grounding the chassis of the mixer to the power amplifiers with a large gauge wire helps. And by the same token, isolating the two when they are installed in the same rack may have a quieting effect. A word of caution: Don't do anything with Level controls up, power on, or under any condition that could cause damage to delicate loudspeakers and ears. Make your changes with the system off, then power up carefully to make sure you haven't made matters worse. Surprises are nice on birthdays and Christmas, and rarely any other time. If hum problems only exist on the Phono Inputs, there is always a possibility for experimental troubleshooting at this end also. Experience has shown that just because the manufacturers put ground wires on them, they are not always connected!Some turntables even have two ground wires, one for the tone arm and one for the chassis. Sometimes only one of these should be connected for optimum signal-to-noise, sometimes both, sometimes none. The rule is: "Whatever works, works. " Manual- OPERATING INSTRUCTIONS INITIAL OPERATION Operation of the MP 24z is fairly straightforward, deviating only slightly from other products of its type. Assuming at least one turntable is connected and assigned to PHONO 1, operation consists of the following: Make sure all faders are set to zero, the MIC, LOOP, EQ, and ACTIVE CROSSFADER are all disengaged, (switches out) and that all rotary LEVEL controls are either fully counter-clockwise or in their center detents, whichever applies. Before much travel is reached on the faders, the results should be heard. If not, shut everything down and recheck connections, power to the mixer (look for the yellow POWER light) and ancillary devices (EQs, crossovers, amplifiers, etc. ) Once an output is established from the turntable, go ahead and try everything else. Assign all Inputs to the Channels they will be used, and test the system. REAR PANEL ADJUSTMENTS There are some controls on the rear panel which need to be set. Set the METER SENSITIVITY ADJUST so the system is at maximum level, (usually just short of amplifier clipping). Run the system up to this maximum level and turn the METER SENSITIVITY ADJUST so that the highest peaks on the PEAK PROGRAM METER occasionally hit the +8 dB indicator. This warns the operator that further pressure on the throttle will overdrive the system. At this point check the MAXIMUM OUTPUT GAIN REDUCTION control so that with the MASTER LEVEL at "10", the meter responds as it did in the previous step. [. . . ] Remove the fourteen (14) nuts from the various ¼" connectors on the rear panel. Remove the five (5) philips-head screws holding the RCA connector assemblies and the one securing the bracket in the center area of the rear panel (near LIGHT OUTPUT LEVEL). Remove the three (3) knobs from the rotary controls protruding through the rear. Carefully lift off the chassis, spreading it slightly so it clears the obstructions created by the circuit boards.
